WIRE-DRAWING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 666,048, dated January 15, 1901.

Application filed April 14, 1899. serial No. 712,962. (No model.)

To @ZZ whom. it may concern,.-

Be it known that I, THEODORE M. Foo'rn, a citizen of the United States of America, residing in the borough of Brooklyn, city and State of New York, have invented certain new and useful Improvements in Wire-Drawing Machines, of which the following is a specification.

My invention relates to Wire-drawing machinery.

I will describe a wire-drawing machine and also a reel which may be used in conjunction with the wire-drawing machine, each embodying my invention, and then point out the novel features thereof in the claims.

In the accompanying drawings, Figure l is a side elevation of a series of Wire-drawing machines and a part of a reel, (the Whole reel being shown in Fig. 10,) each embodying my invention, with the electric circuits employed therein conventionally shown. Fig. 2 is a top view of Fig. 1, part of said view being in horizontal section taken on the line 2 2, Fig. l. Fig. 3 is a longitudinal sectional View taken on the line 3 3, Fig. 2. Fig. 4 is a transverse vertical sectional view taken on the line 4 4, Fig. l. Fig. 5 is a transverse vertical sectional view taken on the line 5 5, Fig. l. Fig. 6 is an enlarged horizontal sectional view taken on the line 6 6 of Fig. 7. Fig. 7 is a transverse sectional view taken on the line 7 7, Fig. 6. Fig. 8 is a view similar to Fig. 7, but showing the position of the parts of the clutch after the magnets have been energized. Fig. 9 is a transverse sectional view taken on the line 9 9, Fig. 6. Fig. 10 is a side elevation of the reel in which my invention is embodied and a part of a wire-drawing machine. Fig. 11 is a top view of Fig. l0. Fig. 12 is an enlarged ltransverse vertical sectional view` taken on the line 12 12, Fig. 10. Fig. 13 is a sectional view taken on the line 13 13, Fig.

arranged as to give a successive and continuous reduction to a Wire A3.

H represents a reel placed at the end ofA the series of machines and which in the example shown also acts as a wire-drawing machine, as it gives the final reduction to the wire. Each machine and the reel may comprise a bed or base a and uprights a. Each machine and, if desired, the reel is provided with a l die-box a2, containing a lubricating liquid,

and a die a3, located in said box. Located in advance of each die on each machine is a drawing-head B, which is rotated as hereinafter described to draw the Wire.' As shown, each drawinghead delivers by way of an idler or idlers to the drawing-head on an adjacent machine, or a drawing-head may deliver directly to a reel. Each machine is provided with means for regulating the draft of a drawing-head, and these means are controlled bythe wire delivered from one drawing-head to another. In case of a drawinghead delivering directly to a reel l provide means intermediate the drawing-head and reel for regulating the draft of the reel through the die, which means are also controlled by the wire delivered from the drawing-head to the reel. l The means for regulating the draft of the drawing-head or reel comprise a clutch, vwhich is preferably an electromagnetic friction-clutch. The circuitof the magnets in each clutch includes a controller, which controller is in the path of the wire delivered from one drawing-head to another. The controller is of such construction that when excess tension is put upon the Wire it Will be operated to open the circuit of the clutch of the drawing-head to which the wire is being delivered to stop that drawing-head from operating the Wire, and thus relieve the Wire of tension.

The machines are all of substantially the same construction, so that the following description, which is of one machine, Willapply equally to all the machines. y

All the machines combined may be considered as a single machine in which a continuous and successive reduction of Wire is effected.

O represents a shaft suitably journaled in the uprights a', and c pulleys provided on one IOO and b represents a gear-wheel fast on said shaft, which meshes with apinion d, that is looseon the shaft C.

In advance of the drawing-head B, I preferably arrange a' second drawing-head B', that is fast on a shaft b2, which shaft is suitablyV journaled in the uprights ct'.

b3 represents a gear-wheel fast on the shaft b2, which gear-wheel meshes with the pinion d. It will therefore be seen that when the shaft C is coupled or uncou pled with the shaft b it will also be coupled or uncoupled with the shaft b2. I wish it to be understood, however, that the drawing-head B may be omitted, and also, if desired, the clutch D may be provided on the shaft of the drawinghead and so arranged thereon that the` head will be rotated when the magnets of the clutch are energized and stopped from] rotation when the magnets are denergized. This is the arrangement preferred for the reel, as will be hereinafter set forth.

The drawing-head B delivers thewire to an idfler E, carried on a shaft e, which is journaled in extensionsa4 of the uprights a.

i From the idler E the wire passes over anl idler F to another idler E', carri-ed on a, shafte',

which is journaled in the uprights a'. The wire then passes from this idler to a disk-die onan adjacent machine. The idler F iscarried on a shaft f, which isjournaledin swinging arms f', which arms are fulcrumed` on a rod a5, held in extensions a6 of the uprights a". Connected to one of the arms is a lever or extension g, which m-ay formv part of a controller for one of the clutches D. The controller carried by each machine preferably does not actuate the clutch for the drawinghead of the same machine, but the clutch for the drawing-head of an adjacent machine. With this arrangement the wire intermediate the drawingehead will be relieved of all eX- cess tension, so that a very high speed may t be obtained for the machines without atthe controller to stopthe reel from further rotation. The form of clutch that-I preferably employ is-shown more particularly in-Figs.y 6, 7, 8, and 9.

The piniondis loosely mounted upon=the sha-ft C and' isprovided withasleeved on one side thereof and a sleeve d2 on the other Vsecured to the plate d5.

side thereof. The pinion d also vcarries a circular plate d3, which may be integral therewith.

d4 represents an integral peripheral flange extending at right angles from the plate d3.

C118 represents a plate removably1 connected with the flange d4. l

(Z5 represents a circular plate loosely carried on the sleeve d2, and'd6 an integral peripheral flange thereon, which extends in a direction from the plate d5 that is parallel with the ange d4. The iiange d6 is cut away, as shown at d7, to accommodate a block d8, that is carried by the flange d4.

di represents a series of magnets which are Each of these magnets is provided with two windings of wire, one of which windings, 'and preferably the outer winding, is composed of a coarser wire than the inner winding. The two windings of each magnet may be wound on the core in opposite directions, so that when a current is passed through both windings inthe same direction the magnetism of the inner winding will be opposite to that of the outer winding. Instead the two windings may be wound in the same direction andl currents passed through them inv opposite directions to. obtain the opposite magnetisms. In either case the magnetism of the inner winding is; maintained at all times for the purpose of discharging any residual magnetism of the outer Winding remaining in the core after the-current is cut outv of this winding. In Fig. 7 I have shown in. outline the two windings of wire and the connections between" the magnets. The terminals of the win-dings are passed through insrrlated eyes t', carried in the plate d5, and through an: opening d10 in the plate dthro ugh tubes d to rings or bands to be hereinafter referredto. Opposite Vthe magnets is a circular plate (i12, which turns: with the shaft C.

It ifs provided with a iiange d, which is in.-

about the viiange 113, the plate d3 and pinion d are made tozturn with it, and in this manner the` drawing-head B is made to rotate; The clamping of this band about the fiange Z13 is accomplishedinthe following manner: When the outer windings of the magnets are energized, the plate 61.12 will be attracted by the magnets, and` through the attraction exerted bythe magnets the plate d5 will move with theplate (112. As the plate d5 is moved with the plate e112 the band d. will be tightened or clamped` about the iiange C113, asshownv in Fig.l 8. r[TheY friction between, theband and flange C213 will prevent relative movement of these parts, and thus cause the flange toV move the platedsand pinion d. As soon as the current is cut out of the outer windings of IIO the magnets, the cores Will be deenergized of the magnetism produced by the outer windingsnand the plate (i12 will rotate without the plate d3.

(115 and d1@ represent the terminals of the outer windings of the magnets and d one terminal of the inner windings, the other terminal being connected with one of the terminals of the outer winding.

Z represents a battery located in the terminals of the ou ter windings, to which the terminal of the inner winding is secured. The terminal d of the winding is secured to the terminal of the outer winding just referred to in such manner that the battery Z will be included between the terminals of the inner windings, so that the inner windings of the magnets will always contain current,and thus energize the core. The magnetism so produced is not sufficient to attract the plate (112 and cause the plate d5 to rotate with it. The terminals d, di, and d are connected with contact-pieces l 2 3, which bear upon rings or bands 4, 5, and 6. These rings or bands are separated and secured to a sleeve of insulation 7, which is loose upon the sleeve d.

G represents a controller provided in the circuit of the outer windings of the magnet. As shown, the controller comprises the arm g and the adjustable screw g', which is carried in a bracket extension g2 of one of the uprights. The controller on each machine is so arranged as to be normally closed, in which position the magnets of the clutch will be energized and the drawing-head will be rotated. As soon as there is any excess tension on the wire intermediate the drawingheads on any two machines the idler F is rocked, so as to move the arm g, and thus open the circuit.

g3 represents a spring, one end of which is connected with the arm g, while the other end is connected with a screw g4, which is adjustable in an extension g5. By adjusting the screw g4 the controller may be made to open under the slightest tension or a very heavy tension.

Referring now to the reel shown in Figs. l() and ll, H represents the reel which winds the wire after its final reduction through its die. The reel is keyed to ashaft h, which is journaled in extensions of the uprights ct', audits rotation is effected through the clutch D, which is provided on the shaft h. The parts of the clutch and their relative positions are the same as hereinbefore described, except that the sleeve d is extended to carry the driving-pulley c. The driving-pulley is belted with the other pulleys in such a manner that when the reel isV coupled to the shaft it will rotate in thedirection of the arrow, Fig. l0. Referring now to Figs. l2, 13, and la, it will be seen that when the pulley c is rotated the sleeve d and plate d3 will rotate with it. The plate d5 will also rotate with the sleeve and plate d3 by reason of the band C113 having its ends connected with these parts. The normal position ot' the partsduring` rotation and without the-magnets being energized is shown in Fig. 13. As soon, however, as the magnets are energized the attraction thereof will retard the movement of the plate d5, and thus cause the band @Z13 to be tightened around the iiange of plate d, as shown in Fig. 14. The plated12 will then rotate with the sleeve d', and as it is keyed to the shaft of the reel the end will be caused to rotate with it. The controller employed for the magnets is the same as hereinbefore described, except that it is swung from the shaft h. The operation ofthe controller is the same as hereinbefore described.

.I represents adevice for annealing the wire. It comprises a suitable support 2, which is secured at one end to one of the uprights d and provided with a yoke i3 at its other end. Arms 114 are secured to the yoke t3, and connected with the arms t4 are two terminals of a transformer-coil 115. A low potential current is sent through the coil to heat the arms t4 to an annealing temperature. passes from the drawing-head it is passed under the arms'z'4, and thus annealed.
